I beg to disagree. Installing multiple handlers on signals is a very crucial feature in my mind. For instance, without it it's almost impossible to have a really feature-rich designer tool which produce live dialogs (like Qt's Designer does). And how do you enable two controls when a checkbox is pressed? You're forced to write your own little function which calls the enable function? That's wasted code IMO. > and then I find that > multiple-handler systems (e.g. gtk signals) tend > to hinder more than they help. Is there a production-ready GUI toolkit that *doesn't* have multiple handlers?
